Your end of times beer

Well, we are just about a month away from the Mayan bíakítun 13 (12/21/2012) which just about any nutjob out there will tell you will be the greatest catastrophe between the Y2K catastrophe and the Unix 2038 catastrophe.

So, in light of our impending doom, hereís a fun topic:

Say the Mayans predicted the Great Beer Catastrophe, in which all but a single style of beer would be wiped from the face of the earth for eternity. That is, nothing but this one beer would ever be produced again. This beer alone would be available at every bar, ball game, and grocery store; for free until the end of time.

Which beer would you choose? What sacred brew do you think you could savor every day for the rest of your life, and never tire of?

Personally for me, I would have to go with either a well-balanced stout or oktoberfest. My current pick would be Left Hand Milk Stout, although having tried fewer than 100 beers, I can say I do not have the most educated opinion.
